1, 202 1 Is the day longer or the night longer after the vernal equinox?

Every time after the vernal equinox, the sky gets darker and darker. The reason why this happens is that from the vernal equinox to the autumnal equinox, the direct point of the sun is north of the equator, so the northern hemisphere is in a state of long days and short nights. With the increase of latitude, the days become longer; Even in the Arctic Circle, there are a few extreme days, but there are not many extreme days. However, there are also special circumstances. In the Arctic, the extreme day can last for about half a year. Because of symmetry, the situation in the southern hemisphere is just the opposite.

2. Why are the days getting longer and longer after the vernal equinox? Since entering the vernal equinox, many people must have found that it gets dark late, mainly because of the problems caused by the operation of the sun. On the day of the vernal equinox, the sun shines almost directly at the equator of the earth, so the day and night around the world are almost equal, each with 12 hours. After the vernal equinox, the direct point of the sun began to move to the northern hemisphere, and the days in the northern hemisphere were longer than the nights.

3. What happened to the length of day and night after the vernal equinox? The length of day and night of the vernal equinox is the same. After the vernal equinox began, the days in the northern hemisphere became longer and the nights became shorter.

The vernal equinox and autumnal equinox in China's 24 solar terms are exactly two days in a year when the sun shines vertically on the equator of the earth. That is to say, one day in the first half of the year is the vernal equinox and the other day in the second half is the autumnal equinox. These two days are very special, and day and night are as long as each other, so they are called vernal equinox and autumnal equinox. After the vernal equinox, the days gradually increase and lengthen, while the nights remain short day by day until the autumnal equinox, and the days are as long as the nights. After the autumnal equinox, the day time is shorter and the night time is longer, and the cycle is one year.
